In my fixed wing project, I enabled actuator control in PX4 in QGroundControl to configure control surfaces. In that section I am doing configuration as described here. However, although at first servos work without error, they start behaving really strange. These behaviours are:
- While testing the servo does not move although at the beginning it moved.
- After that when I try to control it through RC it does not move.
- Sometimes a strange sound occurs on the servo, its temperature rises but it does not work as intended.
Considering these I think that the problem may arise from QGC configuration. The values I use on actuator section:
- Disarm: 900
- Max: 2000
While setting these values, I am trying to provide neutral position when the fixed wing is disarmed. However, I think that the disarm value may not be correct. It should have been 1500. Or, PWM400 is not correct. However, I have not tried changing them yet. I really appreciate if someone could help me about finding what is wrong and control surface configuration.
